He totally deserves it. Shame that it was discounted to get it, but it's quality. I always give exceptions for quality music.
Right now sales alone can't get you the #1, there's streaming, on demand chart and Radio and he's doing great on all these formats. And the song is having success WW.
Quote:
"When I Was Your Man," which marks Mars' fifth single to reach No. 1 on the Hot 100, has exceeded sales of 2 million stateside and 1 million overseas. Mars is among the nominees for the Billboard Music Awards' Milestone Award.
I swear, King fights for his #1 positions each and every time. WIWYM was released 3 months ago and now it's topping the chart also not to mention upon its release, people thought LooH would flop. As I said initially, KING!
i wonder what the next single will be 
probably my favorite song off his new album
